MacGDBp 2.0.2 Released

Posted on April 18, 2020 at 07:00 UTC, filed under the category MacGDBp. Tags: software, MacGDBp,

Today I’m releasing MacGDBp 2.0.2 to address a major issue with the auto-updater and some other minor product bugs.

Somehow when upgrading the Sparkle updater framework when working on MacGDBp 2.0, the auto-update relauncher binary lost its executable bit. This resulted in the auto-update installation hanging indefinitely. Unfortunatley there is no way to automatically recover from this state. Users can run:

chmod +x*

… and re-run the in-product updater. Or simply download version 2.0.2 which has resolved the issue.

MacGDBp 2.0.1 Released

Posted on April 11, 2020 at 07:00 UTC, filed under the category MacGDBp. Tags: software, MacGDBp,

In March I quietly promoted the 2.0 beta 1 release to be the final, stable build. I decided to not do a blog post because there were no changes from the beta build.

Today I’m releasing 2.0.1 to address some issues. Thank you to everyone who reported these bugs. The release also improves dark mode support in the source viewer, which you can see below.

MacGDBp 2.0 Beta 1 Released

Posted on January 4, 2020 at 13:30 UTC, filed under the category MacGDBp. Tags: software, MacGDBp,

While I did state that the first beta of MacGDBp would be out by the end of the year, I decided against pushing a new build before immediately disappearing on holiday for two weeks. But today is the day!

Version 2.0 is not a complete rewrite, but virtually every aspect of the app has been updated and improved. The biggest changes are under-the-hood, particularly around the interaction between the frontend and the remote debugger, which now accurately tracks “transactions.” This allows MacGDBp to fetch the contents of long arrays or large objects without issue. In addition, several components have been refactored to improve the project’s code health and the app’s robustness. These improvements fixed numerous long-standing bugs in the app.

The biggest new feature, by popular demand, is the ability to set symbolic breakpoints. This will pause the debugger any time a function of a given name is called, rather than having to rely solely on file/line breakpoints.

Unfortunately, the app will remain un-sandboxed and not code signed. The Sparkle updater is not yet compatible with the app sandbox. And Apple’s annoying two-factor authentication requirements rule out (for me) obtaining a signing certificate. Sparkle will still verify the updates’ signature, however.

Finally, MacGDBp 2.0 sports a new, unified interface. All of the panels and windows have been collapsed into a single, tabbed window.

See the changelog for the full list of new features and bug fixes.

Looking Towards the Future

Posted on October 28, 2019 at 15:30 UTC, filed under the category MacGDBp. Tags: software, MacGDBp,

First, welcome to the new Blue Static! The site has a fresh coat of paint, it has been made more mobile-friendly, and I have updated much of the content, pruning extremely old things while keeping still-old-but-maybe-interesting items around for posterity. For the first time in the history of the site, Blue Static is no longer powered by PHP: the entire site is now rendered as static files by Hugo.

It has been well over seven years since this site was last updated, and that is because I no longer have the substantial amounts of time I once had to dedicate to Blue Static software. Since I now spend all of my working hours writing and maintaining software, the allure of doing so as a hobby has unfortunately diminished.

Over the past few months, I’ve pondered how to move forward with the various Blue Static projects. I’ll outline some of those decisions now:

MacGDBp still has a large number of loyal users. I’m happy to report that in these intervening years, I’ve worked sporadically on the next major version. The first beta of MacGDBp 2.0 will be released before the end of the year! The entire core debugging engine has been rewritten and made more robust, which has fixed many bugs and added new features. The new version will also be code signed and notarized to be compliant with Apple’s increasingly locked-down macOS.

RGB Converter will remain available for download, but because Apple has removed Dashboard in macOS 10.15 Catalina, the widget will not be updated anymore.

Bugdar is the project that I’ve struggled to make a decision on. It is fairly safe to say that any 2.0 greenfield rewrite will not happen. However all of Blue Static’s bugs remain in the Bugdar instance that runs on this site, so it cannot go anywhere over night. I am not currently enamored with other options, such as Github’s issue tracker, so despite Bugdar’s visible age I will continue to run it for Blue Static’s purposes. There may be an infrequent maintenance update, but I do not expect to make major changes to the software at this time.

What drove these decisions is that I have largely stopped writing software in PHP. It is no longer my language of choice, and my interests have moved on to other programming languages and software domains. MacGDBp remains important to me beacuse others find it useful and the code is still fun to work on.

I’ll close with a teaser: there is at least one new project that I will be publishing in the future under Blue Static. It has to do with email and is geared towards power-users.

Look forward to MacGDBp 2.0 Beta 1 coming to a Sparkle update near you!

MacGDBp 1.4 Released [u]

Posted on February 26, 2011 at 18:08 UTC, filed under the category MacGDBp. Tags: mac os x, MacGDBp,

After a slight delay trying to track down some bugs, I’ve decided to push MacGDBp 1.4 to stable distribution. While this release is not quite perfect and there are a few known issues (listed on the project page), I was tired of blocking the release on relatively minor bugs. This release has been a year in the making, and it makes significant improvements over the 1.3 branch. To find out more about what went into making this new version, check out some of the older posts on the blog.

MacGDBp 1.4 Beta 2

Posted on January 15, 2011 at 05:26 UTC, filed under the category MacGDBp. Tags: Cocoa, mac os x, MacGDBp,

I’m happy to announce MacGDBp 1.4 Beta 2. It’s been nearly a month since the first beta was released and more than 200 people have tested Beta 1. I haven’t received any critical bug reports, which means that the internals are stable enough to ship. Beta 2 is the Release Candidate; barring any significant issues, this will be promoted to Stable in a month or less.

This release has a couple of bug fixes and adds two small enhancements:

MacGDBp 1.4 Beta 1

Posted on December 18, 2010 at 22:17 UTC, filed under the category MacGDBp. Tags: mac os x, MacGDBp,

I’m happy to announce the first beta of MacGDBp 1.4. This release represents nearly a year’s worth of work rewriting the entire internal structure of the application. As mentioned previously, MacGDBp 1.4 now communicates to the backend in an asynchronous manner. Not only does this change increase the robustness of the program, it should no longer beachball while waiting for responses from Xdebug. Because it took such a long time to stabilize this branch, there is very little in the way of new features for this release: almost all the work for this release was done for making the network changes and increasing stability.

One new point to be aware of is that the concept of “reconnect” is gone in this version. Instead, the debugger is now either attached to the backend or is detached. When attached, MacGDBp will start debugging any connections from Xdebug. When detached, MacGDBp will send the “detach” command immediately after receiving any new connections, aborting the debug.

There is one known issue:

MacGDBp 1.4: Becoming Asynchronous

Posted on March 30, 2010 at 04:59 UTC, filed under the category MacGDBp. Tags: MacGDBp,

In between working on Bugdar 2, Phalanx, and Chromium, I’ve also been working on MacGDBp 1.4.

With the 1.3.0 release, I tried to address a couple of issues with the underlying network communication layer (called SocketWrapper, which was an Obj-C bridge to a BSD socket). The primary issue I tried to address was with Unicode characters; MacGDBp really only knows how to deal with ASCII text, which has proven problematic for international users. I tried to address this with the 1.3 branch by switching how data was stored and processed. But the 1.3.0 release was an utter failure from this perspective. It crashed extremely often, which lead to the 1.3.1 release that reverted the new network-layer changes. (That said, the new features introduced by 1.3 have been well-received.)

But the issues with the network layer ran far deeper than just dealing with Unicode text. MacGDBp uses synchronous communication with the debugger engine. When you issue a command (step in/out/over, get source, get properties, etc.), the command would be sent and then the thread would block until it received a response. This is bad, especially because MacGDBp does not use background threads; all the communication happens on the main UI thread. This can lead to beach balling and a bad user experience. So, why did I do this? Because synchronous communication makes for a dead-simple API. Asynchronous communication requires a lot more bookkeeping and works through callbacks.

So, for 1.4.0, I decided it was time to revisit the debugger backend. Rather than just trying to adjust how data is transmitted (ASCII vs. Unicode), I decided to rewrite from scratch the entire Xdebug communication layer. Rather than using raw BSD sockets, the 1.4 branch uses the CFNetwork API. This yields two huge benefits. The first is that all network activity is asynchronous because socket stream events are scheduled on the run loop. When data is available, a callback is executed and the UI is updated (as opposed to blocking the thread while waiting for a response). This also makes the application more robust, because if the response never comes, it will not lock up the entire UI. Secondly, by using a Foundation-level framework, UTF8 support comes pre-baked via the toll-free bridge to NSString.

I’ve been rewriting the back end in my spare time and it’s finally starting to stabilize. This release is still fairly far out, though. This core network change is also leading to a large refactoring of the entire application to make it more easily unit testable in the future. One of the results of this is creating a new LoggingController to record all network activity. The goal with this “hidden feature” is to make it easier to track down causes of bug reports. The log looks like this; it’s not pretty, but it should get the job done:

I haven’t yet selected the set of feature enhancements that are scheduled for this milestone. Before any new feature work can be started, the 1.4 trunk needs to become as stable as the 1.3 branch. If you have any feature requests, please search for or file new issues and vote them up in the bug tracker.
